England great Geoffrey Boycott today blasted captain Alastair Cook's "scrambled brain" and said the team needed to use more common sense to prevent yet another defeat to Australia.

Boycott has been shocked by England's lacklustre efforts during the Ashes tour and laid some of the blame at Cook's feet, saying he appeared frustrated and worn down by the Australian attack. "Australia have worked Alastair out," Boycott said in a column for the West Australian newspaper. "They give him nothing to score off his legs or hip and they are winning the battle."
